More Information
Summary:A system encrypts a number by an authentication key to generate first reference data, transmits a result of an authentication process to the host when first encryption data and the first reference data match each other, encrypts or decrypts verification data with a verification key to generate processing data, and transmits the processing data to the host. The host encrypts the number with the authentication key to generate first encryption data, transmits the first encryption data to the memory system, transmits a request regarding an operation in a first mode to the memory system upon reception of a result of the authentication process, transmits the verification key and the verification data read from a second memory to the system, and generates a success notification indicating that an encryptor is working correctly when the processing data and second reference data match each other.
